imx-gpu-viv: bump to version 6.2.4.p1.2

No changelog was provided by NXP but we can assume it's the latest and
therefore the greatest.

What is known, is that that same version worked both ARM and ARM64.
The support for the latter will be added in a follow-up patch.

This package has been tested with X11, Framebuffer and Wayland
back-ends:
 # cd /usr/share/examples/viv_samples/vdk/
 # ./tutorial7
 # gmem_info
 ... display memory use per PID ...
